Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
In order to solve the above problem, an embodiment of a first aspect of the present invention provides a consumable chip, which can solve the problem of frequent replacement of an identification head, and improve user experience.
Referring to fig. 1 and fig. 2, a consumable chip provided by an embodiment of the present invention is described, as shown in fig. 1, a consumable chip 10 includes a circuit board 1, a main control chip 2, and a protocol conversion unit 3.
As shown in fig. 1, a communication connection contact 11 is provided on the circuit board 1, and the communication connection contact 11 is used for connecting with a probe of an identification head equipped with an external device.
In the embodiment, the number of the communication connection contacts 11 disposed on the circuit board 1 is the same as the number of the probes of the identification head disposed on the external device, that is, the number of the probes of the identification head disposed on the circuit board 1 of the external device is the number of the communication connection contacts 11 disposed on the circuit board 1, and meanwhile, since the number of the probes of the identification head disposed on the external device is determined by the external communication protocol adopted by the external device, the external device can be disposed with only one identification head, and the number of the probes on the identification head is determined according to the external communication protocol, and when the circuit board 1 is designed, the communication connection contacts 11 are disposed according to the number of the probes of the identification head disposed on the external device, so that the external device does not need to be disposed with a plurality of identification heads, and the number of the identification heads is reduced.
For example, if the external communication protocol used by the external device is a single bus communication protocol, the external device is configured as an identification head of one probe, that is, the number of probes on the identification head is one, and therefore, one communication connection contact 11 is correspondingly arranged on the circuit board 1, for example, as shown in fig. 1; alternatively, if the external communication protocol used by the external device is the I2C communication protocol, it means that the external device is configured as an identification head with four probes, that is, the number of probes on the identification head is four, and therefore, four communication connection contacts 11 may be correspondingly provided on the circuit board 1. In this way, the number of identification heads equipped with external equipment is greatly reduced.
It is understood that, without departing from the concept of the present invention, the external device may use a communication protocol that is in accordance with actual needs, and the external device is not limited thereto, and only needs to determine that the number of the probes on the identification head is consistent with the number of the communication connection contacts 11 disposed on the circuit board 1 according to the external communication protocol.
As shown in fig. 1, a main control chip 2 is disposed on a circuit board 1, and the main control chip 2 employs a chip communication protocol. It can be understood that different types of master control chips 2 have different chip communication protocols, and when the consumable chip 10 is designed, the corresponding master control chip 2 can be used according to actual needs without limitation.
And as shown in fig. 2, the protocol conversion unit 3 includes a plurality of protocol interfaces 32 and a connection interface 33, the plurality of protocol interfaces 32 are all connected to the main control chip 2, the connection interface 33 is connected to the communication connection contact 11, and the protocol conversion unit 3 is configured to conduct a target protocol interface corresponding to a chip communication protocol in the plurality of protocol interfaces 32, determine an external communication protocol according to communication data received by the communication connection contact 11, and convert the external communication protocol and the chip communication protocol with each other.
In some embodiments, the protocol conversion unit 3 may be disposed on the circuit board 1, or may be disposed independently of the circuit board 1, which is not limited thereto.
Specifically, the protocol conversion unit 3 stores a plurality of types of communication protocols, such as I2C communication protocol, serial communication protocol, or single bus communication protocol, and a protocol interface is provided for each type of communication protocol, so that a data transmission path between the protocol conversion unit 3 and the main control chip 2 can be formed by connecting the plurality of protocol interfaces 32 to the main control chip 2 and connecting a protocol interface corresponding to the chip communication protocol adopted by the main control chip 2, i.e. a target protocol interface, among the plurality of protocol interfaces 32, to realize data communication between the protocol conversion unit 3 and the main control chip 2, and thus, in this way, any communication protocol can be converted into an external communication protocol by the protocol conversion unit 3, so that the protocol conversion unit 3 can be adapted to the main control chip 2 supporting any communication protocol, the applicability of the protocol conversion unit 3 is improved.
Thus, by the above arrangement, when the main control chip 2 in the consumable chip 10 is operated by an external device, the identification head of the external device arrangement can be directly connected to the communication connection contacts 11 of the consumable chip 10, thus, a data transmission path between the main control chip 2 and the external device is formed by the recognition head, the communication connection contact 11, the connection interface 33, and the target protocol interface, and by using the protocol conversion function of the protocol conversion unit 3, thus realizing the data communication between the external equipment and the main control chip 2 and finishing the operation of the external equipment to the main control chip 2, the user does not need to spend time searching the identification head matched with the main control chip 2, the operation is simple and convenient, and the limitation of the type of the main control chip 2 is not needed, the problem that the user frequently changes the identification head is solved, and the user experience is improved.
The following description will be made by taking the use of the consumable chip as an example with reference to fig. 1 and 2.
Assuming that the external device is a chip data processing device and the external communication protocol adopted by the external device is a single bus communication protocol, the number of probes on the identification head configured for the external device is one, so that the number of the corresponding communication connection contacts 11 in the consumable chip 10 is one, and meanwhile, the connection interface 33 of the protocol conversion unit 3 in the consumable chip 10 is used for being correspondingly connected with the communication connection contacts 11, and the number of the connection interface 33 is also one. It is assumed that the chip communication protocol adopted by the main control chip 2 is the I2C communication protocol, so after the main control chip 2 is connected to the protocol conversion unit 3, a protocol interface corresponding to the I2C communication protocol in the plurality of protocol interfaces 32 is turned on to be used as a target protocol interface, that is, the protocol conversion unit 3 performs data transmission with the main control chip 2 through the protocol interface corresponding to the I2C communication protocol.
Based on the design of the consumable chip 10, when the chip data processing device writes or resets the main control chip 2 in the consumable chip 10, the user can directly connect the identification head of the external device with the communication connection contact 11 of the consumable chip 10, so that the identification head, the communication connection contact 11, the connection interface 33 and the target protocol interface form a data transmission path. Therefore, when the external device sends communication data, the communication data is transmitted into the protocol conversion unit 3 through the identification head and the communication connection contact 11, the protocol conversion unit 3 determines that the external communication protocol is a single-bus communication protocol according to the received communication data, converts the communication data sent by the single-bus communication protocol into data transmitted by a chip communication protocol, namely, data transmitted by an I2C communication protocol, and further sends the data to the main control chip 2 through a protocol interface which is conducted and corresponds to the I2C communication protocol, and the main control chip 2 executes actions such as programming or resetting operation according to the received data; and the main control chip 2 can also send communication data to the protocol conversion unit 3 through the protocol interface corresponding to the I2C communication protocol, and the protocol conversion unit 3 converts the received communication data into data transmitted by the external communication protocol, that is, into the single bus communication protocol, and further transmits the data into the external device through the communication connection contact 11 and the identification head. Therefore, both the main control chip 2 and the external device can perform data transmission through a data transmission path formed by the identification head, the communication connection contact 11, the connection interface 33 and the target protocol interface, and perform mutual conversion on the external communication protocol adopted by the external device and the chip communication protocol through the protocol conversion unit 3, so that the single-wire communication between the external device and the consumable chip 10 is realized, namely, the reset and burning of the main control chip 2 are realized through the single-needle communication, and the probe number is simplified, and the operation is simple and convenient.
According to the consumable chip 10 of the embodiment of the invention, the protocol conversion unit 3 is provided with the plurality of protocol interfaces 32, so that the protocol conversion unit 3 can be suitable for the main control chip 2 supporting any communication protocol, the applicability of the protocol conversion unit 3 is improved, the number of the communication connection contacts 11 matched with the number of the probes of the identification heads equipped for the external equipment is arranged on the circuit board 1, and the arranged communication connection contacts 11 are correspondingly connected with the connection interfaces 33, therefore, after the consumable chip 10 is in communication connection with the outside, the protocol conversion function of the protocol conversion unit 3 is utilized, that is, the external communication protocol adopted by the external equipment and the chip communication protocol are mutually converted, the communication between the main control chip 2 and the external equipment can be realized, the identification heads do not need to be frequently replaced, and the user experience is improved.
In some embodiments, as shown in fig. 2, the protocol conversion unit 3 further includes a unit body 31 and a controller 34.
Wherein a plurality of protocol interfaces 32 and a connection interface 33 are provided on the unit body 31. The controller 34 is disposed on the unit body 31, and the controller 34 is connected to both the protocol interface 32 and the connection interface 33, and is configured to communicate with the target protocol interface, and mutually convert the external communication protocol and the chip communication protocol, that is, the controller 34 controls data transmission of different protocols between the main control chip 2 and the external device, so as to implement communication between the main control chip 2 and the external device.
In some embodiments, the protocol conversion unit 3 is further configured to send a handshake feedback signal in response to the handshake signal received by the communication connection contact 11, that is, after the consumable chip 10 is connected to the external device, the external device sends a handshake instruction to the protocol conversion unit 3, and the protocol conversion unit 3 sends a handshake feedback instruction according to the received handshake instruction, so as to inform that the external device has established normal connection communication with the consumable chip 10, so as to facilitate subsequent data transmission between the external device and the consumable chip 10.
It should be noted that, after the external device sends the handshake instruction to the protocol conversion unit 3, if the handshake feedback instruction sent by the protocol conversion unit 3 is not received, it indicates that the external device and the consumable chip 10 are not successfully connected, and the external device will report an error to remind the user.
In some embodiments, the external device connected to the consumable chip 10 may be a chip data processing device, and the chip data processing device may perform operations such as resetting of the main control chip 2, data burning, model modification, and chip upgrading on the empty chip, so that after the consumable chip 10 and the chip data processing device establish normal communication, both the main control chip 2 and the chip data processing device may perform data transmission through a data transmission path formed by the identification head, the communication connection contact 11, the connection interface 33, and the target protocol interface, the communication data transmitted by the chip data processing device includes at least one of reset data, upgrade data, and update data sent in an external communication protocol, and thus at least one of the reset data, the upgrade data, and the update data is converted into data transmitted in a chip communication protocol by the protocol conversion unit 3, and the data transmitted by the chip communication protocol is sent to the main control chip 2, and the main control chip 2 executes corresponding operation according to the received communication data, so as to realize programming or resetting of the main control chip 2.
It should be noted that, after the main control chip 2 completes the operation corresponding to the communication data transmitted by the chip data processing device, the main control chip 2 sends an operation completion instruction, such as a reset completion instruction, an upgrade completion instruction, or an update completion instruction, to the protocol conversion unit 3, and the protocol conversion unit 3 performs protocol conversion and transmits the protocol conversion to the external device, so as to notify the external device that the programming is completed.

In a third aspect of the present invention, a method for controlling communication of a consumable chip is provided, where the consumable chip provided in the above embodiments includes a protocol conversion unit and a main control chip, and the protocol conversion unit includes a plurality of protocol interfaces connected to the main control chip and a connection interface for receiving external communication data, as shown in fig. 4, the method includes at least steps S1-S3.

In the embodiment, a plurality of types of communication protocols, such as I2C communication protocol, serial communication protocol, or single bus communication protocol, are stored in the protocol conversion unit, and a protocol interface is correspondingly provided for each type of communication protocol, therefore, by connecting a plurality of protocol interfaces with the main control chip and conducting the protocol interface corresponding to the chip communication protocol adopted by the main control chip in the plurality of protocol interfaces, namely the target protocol interface, a data transmission path between the protocol conversion unit and the main control chip can be formed to realize data communication between the protocol conversion unit and the main control chip, by this arrangement, any communication protocol can be converted into an external communication protocol by the protocol conversion unit, therefore, the protocol conversion unit can be suitable for the main control chip supporting any communication protocol, and the applicability of the protocol conversion unit is improved.
In step S2, an external communication protocol is determined according to the communication data received by the connection interface.
In an embodiment, the connection interface of the protocol conversion unit is used for receiving communication data transmitted by the external device, and the number of the connection interfaces set by the protocol conversion unit is consistent with the number of the probes of the identification heads equipped with the external device, so that when the external device operates the main control chip in the consumable chip, communication connection is established between the identification heads configured with the external device and the connection interfaces directly, a user does not need to spend time for searching the identification heads matched with the consumable chip, the operation is simple and convenient, the identification heads do not need to be frequently replaced, and the user experience is improved.
